Print3r

Introduction

Print3r is a command-line tool (without GUI) to print 3d parts (.gcode, .stl, .amf, .3mf, .obj, .off, .scad, .sscad, etc) to 3d printers, utilizing a slicer of your choice (Slic3r, Slic3r PE, PrusaSlicer, SuperSlicer, CuraEngine 3.x, CuraEngine 4.x, CuraEngine 5.x, Cura 15.04 and a few more).

Examples

print3r -p prusa-i3 print cube.scad
print3r -p ender3 -d /dev/ttyUSB1 print cube.stl
print3r preview cube.gcode

Main Features

• print .scad, .stl* or .gcode to 3d printers
• slice .scad or .stl* saving .gcode without printing
• preprocess parts with --scale=<x>,<y>,<z>, --rotate=<x>,<y>,<z>, --translate=<x>,<y>,<z>, --random-placement, --auto-center, --multiply-part=<n>
• use slicer-independent arguments like --temperature=<c>, --layer-height=<h>, --fill-density=<f>, --perimeters=<n>, etc.
• send Gcode from command line arguments with gcode or console interactively with gconsole command
• render Gcode and sliced .stl, .scad into .png image with render command
• preview Gcode using yagv Gcode viewer with preview command
• log lists all past finished prints with all settings used

*) .stl (ascii & binary), and preliminary .amf and .obj supported as well.

To Do / Planned

• slicer agnostic, e.g. support of CuraEngine (just the slicer): done since 0.1.6 with slic3r, slic3r-pe, cura-legacy and cura
• network connectivity, distributed printing via tcp/ip: done since 0.2.0 with client command and --device=tcp:<remote-ip>[:<n>] (n=0 (default),1,2 etc)
• preview gcode in OpenGL/WebGL zoomable views: done with 0.1.6 via external yagv viewer
• multiple extruder support (preferably slicer-independent)

Platform

Primary focus in on Linux (Debian, Ubuntu) and alike platforms like FreeBSD and such.

Requirements

• install openscad, see OpenSCAD.org
• install slic3r, Debian/Ubuntu: apt install slic3r
• optional:
  • recommended: install Slic3r PE
  • recommended: install CuraEngine
  • install CuraEngine Legacy
  • recommended: install FreeCAD2Any which supports FCStd, IGES, STEP and Brep import as well

Environment Variable PRINT3R

You can set any option into PRINT3R environment variable, "<key>=<value>", combined with ":", like:

export PRINT3R "printer=prusa-i3:temperature=190:..."
print3r print cube.scad

Render Example

Instead to actually print parts, you can also let them render into .png image as well (e.g. for documentation purposes or preview):

print3r --output=benchy.png render 3DBenchy.stl
